Elevate the classic rice krispie treat with a gourmet twist. These treats feature nutty brown butter, warm cinnamon-spiced cereal, and a hidden layer of silky dulce de leche. Extra marshmallows create delightfully gooey pockets throughout, while a touch of sea salt brings perfect balance. An impressive no-bake dessert that comes together quickly.
The combination of flavors in these treats has made them a consistent crowd favorite. The caramel notes from the dulce de leche pair beautifully with the warm cinnamon cereal, while brown butter adds a sophisticated nuttiness that sets them apart from traditional recipes.
